Psi Wheel In a Box

wheel is placed inside a cardboard box with plastic cover on top.

This allow visibility of the psi wheel from out side limiting air flow
from surroundings. Two holes are made for two hands to put into the box.

The lids of the holes are close enough to make a minimum air flow
from surroundings

Advantage is I can practice psi training even in an open room.
I could breath normally , with out any doubt that air from nostrils
reach psi wheel directly, Let me say, that's a good relief during practice.

PSI Wheel in side a box

A card board box with transparent top plastic cover is

made for this experiment setup.

Aim was to check exernal air flow is contributing to psi wheel 

movement or not.  Two small opening through which two hands 

can be placed in to the box.  Psi wheel inside is not affected

by air currents out side the box.  Wheel rotates indicating

that there is no contribution of local air currents.
